The idea of treating the trinucleon systems as elementary entities in the elementary particle model (EPM) as an Effective Field Theory has been a success in explaining the weak charge-changing processes in nuclei.The EPM results are found to be as good as those obtained from nuclear microscopic models using two-and three-body forces. We extend this concept to investigate the validity of the elemental nature of A = 3 nuclei through studies of nuclear structure of neutron-rich nuclei. By treating neutron-rich nuclei as primarily made up of tritons as its building blocks, we extract one-and two-triton separation energies of these nuclei.Calculations have been performed here within relativistic mean field (RMF) models with latest interactions.Clear evidence arises of a new shell structure with well-defined predictions of new magic nuclei. These unique predictions have been consolidated by standard one-and two-neutron separation energy calculations.The binding energy per nucleon plots of these nuclei also confirm these predictions. We make unambiguos prediction of six magic nuclei: 24 8 O 16 , 60 20 Ca 40 , 105 35 Br 70 , 123 41 Nb 82 , 189 63 Eu 126 and 276 92 U 184 . PACS numbers:
